King Kong shrimp, also known as Penaeus monodon, belongs to marine shrimp and needs seawater for cultivation. King Kong shrimp is characterized by short culture time, fast growth, high survival rate, strong disease resistance, low incidence and high yield. High-density culture technology of king kong shrimp: choose areas with pollution-free water quality, sufficient water source and both sea and fresh water; Ponds are generally square, rectangular and round; The bottom of the pond should be covered with plastic film, and then covered with loam and silt.
1. Is king kong shrimp cultured in fresh water or seawater?
1. Is King Kong shrimp cultured in fresh water or seawater?
King Kong shrimp, also known as Penaeus monodon, belongs to seawater shrimp, so seawater is needed for cultivation.
2. Characteristics of King Kong Shrimp
(1) The breeding time is short (more than 3 months) and the growth rate is fast.
(2) High reproductive survival rate (above 75%) and good adaptability.
(3) Strong disease resistance and low incidence.
(4) The yield is high, with an yield of more than 750kg per mu.
(5) Long water outlet time, good activity and fresh sales.
Second, the high-density culture technology of king kong shrimp
1, pond construction
(1) The requirements of King Kong shrimp culture pond are similar to those of Penaeus vannamei culture pond. Choose areas with pollution-free water quality, abundant water and both sea and fresh water, with convenient transportation, stable electricity consumption and convenient supply of production materials (feed, medicine, etc.). ) and the treatment and discharge of aquaculture sewage will not cause damage to the natural environment.
(2) Generally, square, rectangular and round ponds are better. It is necessary to consider both the directional flow of water and the utilization rate of land. It is reasonable and cost-effective. Pond area 1-4 mu, suitable for good management and high yield. The water depth shall be kept at1.5-2.5m.. General soil pool 1- 1.5m, high pool 1.5-2.5m or so. ..
(3) The soil pool is generally 1- 1.5m, and the high pool is generally1.5-2.5m. The bottom of the pond should be covered with plastic film, and then covered with loam and silt. The bottom of the earthen pond is flat, and the silt does not exceed10cm; The upper tank is covered with film, and the bottom of the tank is inclined to the sewage outlet (sewage outlet), with a slope of about 1-2%.
2. Water source treatment
Deep well water and surface water are generally used for aquaculture. Those who use deep well water can use it directly, and those who use surface water generally need to set up a reservoir, which accounts for 30-50% of the aquaculture water. The water is precipitated, disinfected and filtered in the reservoir.
3. Feed selection
The eating habits of king kong shrimp are diverse, so the requirements for protein are not high. In the early stage of seedling release, shrimp seedlings can eat algae and zooplankton in the pond. However, in order to improve the survival rate and adaptability to the environment, shrimp slices and opening material were fed on the day of seedling release, and high-quality compound feed or fermented materials were selected five days later.
Step 4 supplement nutrition
(1) In the early stage of aquaculture, fermented materials are generally used for feeding. You can also use compound feed and add probiotics (carbon source supplement solution, compound lactic acid bacteria solution, etc.). ) according to the ratio of 1% and proper amount of vitamins, and keep mixed feeding.
(2) Feed Hunting Arc (5g/kg feed) or Jianwei Baibiankang (10- 15g/kg feed) once every five days, and keep it for two days, so as to protect intestinal tract and prevent Vibrio infection.
(3) Liver-protecting growth-promoting hormone in the middle and late stage of culture. Jin Weita, Fish and Shrimp Lux, King Cuochang, etc. Be mixed-fed. 5-6 days is a cycle.
(4) 3-4 days before molting, feed Duowei, Shencaoan, Subu 100, etc. So as to promote the orderly and smooth molting in the molting process. Dead algae, sudden change of water quality and climate, feeding vitamin C, fish, shrimp and garlic milk to protect the health of liver and intestine.
5. Daily management
(1) regularly detect water quality indicators such as P-hour value, ammonia nitrogen, nitrite and dissolved oxygen. Ensure that the water quality reaches the standard, and take timely treatment measures when the water quality index exceeds the standard and changes too much.
(2) Check the feeding situation of prawns and adjust the feeding amount in time; Check the health status of prawns, and deal with problems in time.
